Craft CMS has Cloud Metadata SSRF Protection Bypass via DNS Rebinding
ghsa·2026-02-23·CVSS 5.0
CVE-2026-27127 [MEDIUM] CWE-367 Craft CMS has Cloud Metadata SSRF Protection Bypass via DNS Rebinding
Craft CMS has Cloud Metadata SSRF Protection Bypass via DNS Rebinding
## Summary
The SSRF validation in Craft CMS’s GraphQL Asset mutation performs DNS resolution **separately** from the HTTP request. This Time-of-Check-Time-of-Use (TOCTOU) vulnerability enables DNS rebinding attacks, where an attacker’s DNS server returns different IP addresses for validation compared to the actual request.
This is a bypass of the security fix for CVE-2025-68437 ([GHSA-x27p-wfqw-hfcc](https://github.com/craftcms/cms/security/advisories/GHSA-x27p-wfqw-hfcc)) that allows access to all blocked IPs, not just IPv6 endpoints.
## Severity
Bypass of cloud metadata SSRF protection for all blocked IPs
## Required Permissions
Exploitation requires GraphQL schema permissions for:
- Edit assets in the `` volume
